2 3 Fix varsigma to use U+03C2 (Greek small letter final sigma ς) 4 instead of incorrect U+03C1 (Greek small letter rho ρ). 5 6 Co-Authored-By: Claude Opus 4.5 <[email protected]>
2 3 Add 20 new symbol mappings to supportedLatexSymbols dictionary: 4 5 Greek variants: 6 - varkappa (U+03F0), digamma (U+03DD), Digamma (U+03DC) 7 8 Arrows: 9 - longmapsto (U+27FC), hookrightarrow (U+21AA), hookleftarrow (U+21A9) 10 11 Slanted inequalities: 12 - leqslant (U+2A7D), geqslant (U+2A7E) 13 14 Precedence relations: 15 - preceq (U+2AAF), succeq (U+2AB0) 16 17 Turnstile relations: 18 - vdash (U+22A2), dashv (U+22A3), bowtie (U+22C8) 19 20 Binary operators: 21 - diamond (U+22C4) 22 23 Hebrew letters: 24 - beth (U+2136), gimel (U+2137), daleth (U+2138) 25 26 Miscellaneous: 27 - varnothing (U+2205), Box (U+25A1), measuredangle (U+2221) 28 29 Co-Authored-By: Claude Opus 4.5 <[email protected]>
2 3 Add 9 new test functions covering all Priority 1 symbol additions: 4 - testGreekVariants: varkappa, digamma, Digamma and existing variants 5 - testVarsigmaCorrectUnicode: verify varsigma maps to U+03C2 (final sigma) 6 - testNewArrows: longmapsto, hookrightarrow, hookleftarrow 7 - testSlantedInequalities: leqslant, geqslant 8 - testPrecedenceRelations: preceq, succeq 9 - testTurnstileRelations: vdash, dashv, bowtie 10 - testDiamondOperator: diamond binary operator 11 - testHebrewLetters: aleph, beth, gimel, daleth 12 - testMiscSymbols: varnothing, Box, measuredangle 13 14 Co-Authored-By: Claude Opus 4.5 <[email protected]>

Summary
This PR adds Priority 1 LaTeX symbols and 48 negated relation symbols from amssymb.
Priority 1 Symbol Additions
Bug Fix:
New Symbol Mappings (18 symbols):
Note: digamma (U+03DD) and Digamma (U+03DC) were initially added but removed as they are not supported by Latin Modern Math font.
Negated Relations (48 symbols)
